Gentlemen:

     Hub Group, Inc., a Delaware corporation (the "Company"), proposes to sell
to the several underwriters (the "Underwriters") named in Schedule I hereto for
whom you are acting as representatives (the "Representatives") __________ shares
of the Company's Class A Common Stock, $.01 par value (the "Firm Shares"). The
respective amounts of the Firm Shares to be so purchased by the several
Underwriters are set forth opposite their names in Schedule I hereto. The
Company is sometimes referred to herein as the "Seller." The Company also
proposes to sell at the Underwriters' option an aggregate of up to __________
additional shares of the Company's Class A Common Stock (the "Option Shares") as
set forth below.

     As the Representatives, you have advised the Company (a) that you are
authorized to enter into this Agreement on behalf of the several Underwriters
and (b) that the several Underwriters are willing, acting severally and not
jointly, to purchase the numbers of Firm Shares set forth opposite their
respective names in Schedule I, plus their pro rata portion of the Option Shares
if you elect to exercise the over-allotment option in whole or in part for the
accounts of the several Underwriters. The Firm Shares and the Option Shares (to
the extent the aforementioned option is exercised) are herein collectively
called the "Shares."

                                       1

 
     In consideration of the mutual agreements contained herein and of the
interests of the parties in the transactions contemplated hereby, the parties
hereto agree as follows:


     1.   Representations and Warranties of the Company.
          ----------------------------------------------


          The Company represents and warrants to each of the Underwriters as
          follows:

          (a)  A registration statement on Form S-3 (File No. 333-_______) with
     respect to the Shares has been prepared by the Company in conformity in all
     material respects with the requirements of the Securities Act of 1933, as
     amended (the "Act"), and the Rules and Regulations (the "Rules and
     Regulations") of the Securities and Exchange Commission (the "Commission")
     thereunder and has been filed with the Commission. The Company has complied
     with the conditions for the use of Form S-3. Copies of such registration
     statement, including any amendments thereto, the preliminary prospectuses
     (meeting the requirements of the Rules and Regulations in all material
     respects) contained therein and the exhibits, financial statements and
     schedules, as finally amended and revised, have heretofore been delivered
     by the Company to you. Such registration statement, together with any
     registration statement filed by the Company pursuant to Rule 462 (b) of the
     Act, herein referred to as the "Registration Statement," which shall be
     deemed to include all information omitted therefrom in reliance upon Rule
     430A and contained in the Prospectus referred to below, has become
     effective under the Act and no post-effective amendment to the Registration
     Statement has been filed as of the date of this Agreement. "Prospectus"
     means the form of prospectus first filed with the Commission pursuant to
     Rule 424(b). Each preliminary prospectus included in the Registration
     Statement prior to the time it becomes effective is herein referred to as a
     "Preliminary Prospectus." Any reference herein to the Registration
     Statement, any Preliminary Prospectus or to the Prospectus shall be deemed
     to refer to and include any documents incorporated by reference therein,
     and, in the case of any reference herein to any Prospectus, also shall be
     deemed to include any documents incorporated by reference therein, and any
     supplements or amendments thereto, filed with the Commission after the date
     of filing of the Prospectus under Rules 424(b) or 430A, and prior to the
     termination of the offering of the Shares by the Underwriters.

          (b)  The Company has been duly organized and is validly existing as a
     corporation in good standing under the laws of the State of Delaware, with
     corporate power and authority to own or lease its properties and conduct
     its business as described in the Registration Statement. Each of the
     subsidiaries of the Company as listed in Exhibit 21 to Item 16(a) of the
     Registration Statement (collectively, the "Subsidiaries") has been duly
     organized and is validly existing as a corporation, limited liability
     company, limited partnership or general partnership in good standing, if
     applicable, under the laws of the jurisdiction of its incorporation or
     organization with power and authority to own or lease its properties and
     conduct its business as described in the Registration Statement. The

                                       2

 
     Company and each of the Subsidiaries are duly qualified to transact
     business in all jurisdictions in which the conduct of their business
     requires such qualification, except where the failure to be so qualified
     would not result in any material adverse change in the earnings, business,
     management, properties, assets, rights, operations or condition (financial
     or otherwise) of the Company and the Subsidiaries taken as a whole.  The
     outstanding shares of capital stock of the corporate Subsidiaries and the
     partnership interests in the partnership Subsidiaries have been duly
     authorized, if applicable, and validly issued, except for general
     partnership interests, are fully paid and non-assessable, and, except to
     the extent shown in Exhibit A hereto, such capital stock and partnership
     interests owned by the Company, directly or indirectly, are owned free and
     clear of all liens, encumbrances and equities and claims; and no options,
     warrants or other rights to purchase, with the exception of the Company's
     option to acquire the limited partnership interest in each of the Hub
     Partnerships upon the occurrence of certain events, agreements or other
     obligations to issue or other rights to convert any obligations into shares
     of capital stock or ownership interests in the Subsidiaries are
     outstanding.

          (c) The outstanding shares of Class A and Class B Common Stock of the
     Company will be duly authorized and validly issued and will be fully paid
     and non-assessable; the portion of the Shares to be issued and sold by the
     Company have been duly authorized and when issued and paid for as
     contemplated herein will be validly issued, fully paid and non-assessable;
     and no preemptive rights of stockholders of the Company exist with respect
     to any of the Shares or the issue and sale thereof. Neither the filing of
     the Registration Statement nor the offering or sale of the Shares as
     contemplated by this Agreement gives rise to any rights for or relating to
     the registration of any shares of Class A or Class B Common Stock.

          (d)  The information set forth under the caption "Capitalization" in
     the Prospectus is true and correct as of the dates presented. All of the
     Shares conform to the description thereof contained in the Registration
     Statement in all material respects. The form of certificates for the Shares
     conforms to the corporate law of the State of Delaware.

          (e)  The Commission has not issued an order preventing or suspending
     the use of any Prospectus relating to the proposed offering of the Shares
     nor to the knowledge of the Company instituted proceedings for that
     purpose. The Registration Statement contains, and the Prospectus and any
     amendments or supplements thereto will contain, all statements which are
     required to be stated therein by, and will conform in all material
     respects, to the requirements of the Act and the Rules and Regulations. The
     documents incorporated by reference in the Prospectus, at the time filed
     with the Commission conformed, in all respects to the requirements of the
     Securities Exchange Act of 1934 or the Act, as applicable, and the rules
     and regulations of the Commission thereunder. The Registration Statement
     and any amendment thereto do not contain, and will not contain, any untrue
     statement of a material fact and do not omit, and will not omit, to state
     any material fact required to be stated therein or necessary to make the
     statements therein not

                                       3

 
     misleading. The Prospectus and any amendments and supplements thereto do
     not contain, and will not contain, any untrue statement of material fact;
     and do not omit, and will not omit, to state any material fact required to
     be stated therein or necessary to make the statements therein, in the light
     of the circumstances under which they were made, not misleading; provided,
     however, that the Company makes no representations or warranties as to
     information contained in or omitted from the Registration Statement or the
     Prospectus, or any such amendment or supplement, in reliance upon, and in
     conformity with, written information furnished to the Company by or on
     behalf of any Underwriter through the Representatives, specifically for use
     in the preparation thereof.

          (f)  The condensed consolidated financial statements of the Company
     and the Subsidiaries, together with related notes and schedules as
     incorporated by reference in the Registration Statement, present fairly the
     financial position and the results of operations and cash flows of the
     Company and the Subsidiaries, as the case may be, at the indicated dates
     and for the indicated periods. Such financial statements and related
     schedules have been prepared in accordance with generally accepted
     principles of accounting, consistently applied throughout the periods
     involved, except as disclosed therein, and all adjustments necessary for a
     fair presentation of results for such periods have been made. The summary
     financial and statistical data included in the Registration Statement
     present fairly the information shown therein and such data has been
     compiled on a basis consistent with the financial statements presented
     therein and the books and records of the Company. The pro forma financial
     information included in the Registration Statement and the Prospectus
     present fairly the information shown therein, have been properly compiled
     on the pro forma bases described therein, and, in the opinion of the
     Company, the assumptions used in the preparation thereof are reasonable and
     the adjustments used therein are appropriate to give effect to the
     transactions or circumstances referred to therein.

          (g)  Arthur Andersen LLP, who have certified certain of the financial
     statements filed with the Commission as part of the Registration Statement,
     are independent public accountants as required by the Act and the Rules and
     Regulations.

          (h)  Except as set forth in the Registration Statement, there is no
     action, suit, claim or proceeding pending or, to the knowledge of the
     Company, threatened against the Company, or any of the Subsidiaries before
     any court or administrative agency or otherwise which if determined
     adversely to the Company, or any of its Subsidiaries, might result in any
     material adverse change in the earnings, business, management, properties,
     assets, rights, operations or condition (financial or otherwise) of the
     Company, and the Subsidiaries taken as a whole or to prevent the
     consummation of the transactions contemplated hereby.

          (i)  The Company and the Subsidiaries have good and marketable title
     to all of the properties and assets reflected in the financial statements
     (or as described in the

                                      -4-

 
     Registration Statement) hereinabove described, subject to no lien,
     mortgage, pledge, charge or encumbrance of any kind except those reflected
     in such financial statements (or as described in the Registration
     Statement) or which are not material in amount. The Company and the
     Subsidiaries occupy their leased properties under valid and binding leases
     conforming in all material respects to the description thereof set forth in
     the Registration Statement.

          (j)  The Company and the Subsidiaries have filed all Federal, State,
     local and foreign income tax returns which have been required to be filed
     and have paid all taxes indicated by said returns and all assessments
     received by them or any of them to the extent that such taxes have become
     due and are not being contested in good faith. All tax liabilities have
     been adequately provided for in the financial statements of the Company and
     the Subsidiaries, as the case may be.

          (k)  Since the respective dates as of which information is given in
     the Registration Statement, as it may be amended or supplemented, there has
     not been any material adverse change or any development involving a
     prospective material adverse change in or affecting the earnings, business,
     management, properties, assets, rights, operations or condition (financial
     or otherwise), of the Company and the Subsidiaries taken as a whole,
     whether or not occurring in the ordinary course of business, and there has
     not been any material transaction entered into or any material transaction
     that is probable of being entered into by the Company or the Subsidiaries,
     other than transactions in the ordinary course of business and changes and
     transactions described in the Registration Statement, as it may be amended
     or supplemented. The Company and the Subsidiaries have no material
     contingent obligations which are not disclosed in the financial statements
     which are included in the Registration Statement.

          (l)  None of the Company nor any of the Subsidiaries is or with the
     giving of notice or lapse of time or both, will be, in violation of or in
     default under its Charter, By-Laws or partnership agreement or under any
     material agreement, lease, contract, indenture or other instrument or
     obligation to which it is a party or by which it, or any of its properties,
     is bound and which violation or default is of material significance in
     respect of the business, management, properties, assets, rights, operations
     or condition (financial or otherwise) of the Company and the Subsidiaries
     taken as a whole. The execution and delivery of this Agreement and the
     consummation of the transactions herein contemplated and the fulfillment of
     the terms hereof will not conflict with or result in a breach of any of the
     terms or provisions of, or constitute a default under, any indenture,
     mortgage, deed of trust or other material agreement or instrument to which
     the Company or any Subsidiary is a party, or of the Charter, By-Laws or
     partnership agreement of the Company or any Subsidiary or any order, rule
     or regulation applicable to the Company or any Subsidiary of any court or
     of any regulatory body or administrative agency or other governmental body
     having jurisdiction.

                                      -5-

 
          (m)  Each approval, consent, order, authorization, designation,
     declaration or filing by or with any regulatory, administrative or other
     governmental body necessary in connection with the execution and delivery
     by the Company of this Agreement and the consummation of the transactions
     herein contemplated (except such additional steps as may be required by the
     Commission, the National Association of Securities Dealers, Inc. (the
     "NASD") or such additional steps as may be necessary to qualify the Shares
     for public offering by the Underwriters under state securities or Blue Sky
     laws) has been obtained or made and is in full force and effect.

          (n)  The Company and each of the Subsidiaries holds all material
     licenses, certificates and permits from governmental authorities which are
     necessary to the conduct of their businesses; and neither the Company nor
     any of the Subsidiaries has infringed any patents, patent rights, trade
     names, trademarks or copyrights, which infringement is material to the
     business of the Company and the Subsidiaries taken as a whole.

          (o)  Neither the Company, nor to the Company's best knowledge, any of
     its affiliates, has taken or may take, directly or indirectly, any action
     designed to cause or result in, or which might reasonably be expected to
     constitute, the stabilization or manipulation of the price of the shares of
     Class A Common Stock to facilitate the sale or resale of the Shares.

          (p)  Neither the Company, nor to the Company's best knowledge, any of
     its affiliates, has taken or may take, directly or indirectly, any action
     designed to cause or result in, or which has constituted or which might
     reasonably be expected to constitute, the stabilization or manipulation of
     the price of the shares of Common Stock to facilitate the sale or resale of
     the Shares. The Company acknowledges that the Underwriters may engage in
     passive market making transactions in the Shares on The Nasdaq Stock Market
     in accordance with Rule 103 under Regulation M of the Exchange Act.

          (q)  None of the Company nor any Subsidiary is an "investment company"
     within the meaning of such term under the Investment Company Act of 1940
     and the rules and regulations of the Commission thereunder.

          (r)  The Company and Hub City Terminals, Inc. ("Hub Chicago") maintain

     assurances that (i) transactions are executed in accordance with

     accountability for assets; (iii) access to assets is permitted only in
     accordance with management's general or specific authorization; and (iv)
     the recorded accountability for assets is compared with existing assets at
     reasonable intervals and appropriate action is taken with respect to any
     differences.

          (s)  The Company and each of the Subsidiaries carry, or are covered

     "Department"), whichever date is later, the Company will provide the
     Department notice of such business or change, as appropriate, in a form
     acceptable to the Department.

     2.   Purchase, Sale and Delivery of the Firm Shares.
          -----------------------------------------------

          (a)  On the basis of the representations, warranties and covenants
     herein contained, and subject to the conditions herein set forth, the
     Company agrees to sell to the Underwriters and each Underwriter agrees,
     severally and not jointly, to purchase, at a price of $_____ per share, the
     number of Firm Shares set forth opposite the name of each Underwriter in
     Schedule I hereof, subject to adjustments in accordance with Section 9
     hereof. The number of Firm Shares to be purchased by each Underwriter from
     each Seller shall be as nearly as practicable in the same proportion to the
     total number of Firm Shares being sold by each Seller as the number of Firm
     Shares being purchased by each Underwriter bears to the total number of
     Firm Shares to be sold hereunder.

          (b)  Payment for the Firm Shares to be sold hereunder is to be made in
     same day funds via wire transfer to the order of the Company for the shares
     to be sold by it against delivery of certificates therefor to the
     Representatives for the several accounts of the Underwriters. Such payment
     and delivery are to be made at the offices of Alex. Brown & Sons
     Incorporated, One South Street, Baltimore, Maryland, at 10:00 a.m.,
     Baltimore time, on the third business day after the date of this Agreement
     or at such other time and date not later than five business days thereafter
     as you and the Company shall agree upon, such time and date being herein
     referred to as the "Closing Date." (As used herein, "business day" means a
     day on which the New York Stock Exchange is open for trading and on which
     banks in New York are open for business and not permitted by law or
     executive order to be closed.) The certificates for the Firm Shares will be
     delivered in such denominations and in such registrations as the
     Representatives request in writing not

                                      -7-

 
     later than the second full business day prior to the Closing Date, and will
     be made available for inspection by the Representatives at least one
     business day prior to the Closing Date.

          (c)  In addition, on the basis of the representations and warranties
     herein contained and subject to the terms and conditions herein set forth,
     the Company hereby grants an option to the several Underwriters to purchase
     the Option Shares at the price per share as set forth in the first
     paragraph of this Section 2. The option granted hereby may be exercised in
     whole or in part by giving written notice (i) at any time before the
     Closing Date and (ii) only once thereafter within 30 days after the date of
     this Agreement, by you, as Representatives of the several Underwriters, to
     the Company setting forth the number of Option Shares as to which the
     several Underwriters are exercising the option, the names and denominations
     in which the Option Shares are to be registered and the time and date at
     which such certificates are to be delivered. The time and date at which
     certificates for Option Shares are to be delivered shall be determined by
     the Representatives but shall not be earlier than three nor later than 10
     full business days after the exercise of such option, nor in any event
     prior to the Closing Date (such time and date being herein referred to as
     the "Option Closing Date"). If the date of exercise of the option is three
     or more days before the Closing Date, the notice of exercise shall set the
     Closing Date as the Option Closing Date. The number of Option Shares to be
     purchased by each Underwriter shall be in the same proportion to the total
     number of Option Shares being purchased as the number of Firm Shares being
     purchased by such Underwriter bears to the total number of Firm Shares,
     adjusted by you in such manner as to avoid fractional shares. The option
     with respect to the Option Shares granted hereunder may be exercised only
     to cover over-allotments in the sale of the Firm Shares by the
     Underwriters. You, as Representatives of the several Underwriters, may
     cancel such option at any time prior to its expiration by giving written
     notice of such cancellation to the Company. To the extent, if any, that the
     option is exercised, payment for the Option Shares shall be made on the
     Option Closing Date in same day funds via wire transfer to the order of the
     Company against delivery of certificates therefor at the offices of Alex.
     Brown & Sons Incorporated, One South Street, Baltimore, Maryland.

     3.   Offering by the Underwriters.
          -----------------------------

          It is understood that the several Underwriters are to make a public
     offering of the Firm Shares as soon as the Representatives deem it
     advisable to do so. The Firm Shares are to be initially offered to the
     public at the initial public offering price set forth in the Prospectus.
     The Representatives may from time to time thereafter change the public
     offering price and other selling terms. To the extent, if at all, that any
     Option Shares are purchased pursuant to Section 2 hereof, the Underwriters
     will offer them to the public on the foregoing terms.

                                      -8-

 
          It is further understood that you will act as the Representatives for
     the Underwriters in the offering and sale of the Shares in accordance with
     a Master Agreement Among Underwriters entered into by you and the several
     other Underwriters.

     4.   Covenants of the Company.
          -------------------------

          The Company covenants and agrees with the several Underwriters that:

          (a)  The Company will (A) use all commercially reasonable efforts to
     cause the Registration Statement to become effective or, if the procedure
     in Rule 430A of the Rules and Regulations is followed, to prepare and
     timely file with the Commission under Rule 424(b) of the Rules and
     Regulations a Prospectus in a form approved by the Representatives
     containing information previously omitted at the time of effectiveness of
     the Registration Statement in reliance on Rule 430A of the Rules and
     Regulations and (B) not file any amendment to the Registration Statement or
     supplement to the Prospectus or document incorporated by reference herein
     of which the Representatives shall not previously have been advised and
     furnished with a copy or to which the Representatives shall have reasonably
     objected in writing or which is not in compliance in all material respects
     with the Rules and Regulations and (C) file on a timely basis all reports
     and any definitive proxy or information statements required to be filed by
     the Company with the Commission subsequent to the date of the Prospectus
     and prior to the termination of the offering of the Shares by the
     Underwriters.

          (b)  The Company will advise the Representatives promptly (A) when the
     Registration Statement or any post-effective amendment thereto shall have
     become effective, (B) of receipt of any comments from the Commission, (C)
     of any request of the Commission for amendment of the Registration
     Statement or for supplement to the Prospectus or for any additional
     information, and (D) of the issuance by the Commission of any stop order
     suspending the effectiveness of the Registration Statement or the use of
     the Prospectus or of the institution of any proceedings for that purpose.
     The Company will use all commercially reasonable efforts to prevent the
     issuance of any such stop order preventing or suspending the use of the
     Prospectus and to obtain as soon as possible the lifting thereof, if
     issued.

          (c)  The Company will cooperate with the Representatives in
     endeavoring to qualify the Shares for sale under the securities laws of
     such jurisdictions as the Representatives may reasonably have designated in
     writing and will make such applications, file such documents, and furnish
     such information as may be reasonably required for that purpose, provided
     the Company shall not be required to qualify as a foreign corporation or to
     file a general consent to service of process in any jurisdiction where it
     is not now so qualified or required to file such a consent. The Company
     will, from time to time, prepare and file such statements, reports, and
     other documents, as are

                                      -9-

 
     or may be required to continue such qualifications in effect for so long a
     period as the Representatives may reasonably request for distribution of
     the Shares.

          (d)  The Company will deliver to, or upon the order of, the
     Representatives, from time to time, as many copies of any Preliminary
     Prospectus as the Representatives may reasonably request. The Company will
     deliver to, or upon the order of, the Representatives during the period
     when delivery of a Prospectus is required under the Act, as many copies of
     the Prospectus in final form, or as thereafter amended or supplemented, as
     the Representatives may reasonably request. The Company will deliver to the
     Representatives at or before the Closing Date, four signed copies of the
     Registration Statement and all amendments thereto including all exhibits
     filed therewith, and will deliver to the Representatives such number of
     copies of the Registration Statement (including such number of copies of
     the exhibits filed therewith that may reasonably be requested), including
     documents incorporated by reference herein, and of all amendments thereto,
     as the Representatives may reasonably request.

          (e)  The Company will comply with the Act and the Rules and
     Regulations, and the Securities Exchange Act of 1934 (the "Exchange Act"),
     and the rules and regulations of the Commission thereunder in all material
     respects, so as to permit the completion of the distribution of the Shares
     as contemplated in this Agreement and the Prospectus. If during the period
     in which a prospectus is required by law to be delivered by an Underwriter
     or dealer, any event shall occur as a result of which, in the judgment of
     the Company or in the reasonable opinion of the Underwriters, it becomes
     necessary to amend or supplement the Prospectus in order to make the
     statements therein, in the light of the circumstances existing at the time
     the Prospectus is delivered to a purchaser, not misleading, or, if it is
     necessary at any time to amend or supplement the Prospectus to comply with
     any law, the Company promptly will either (i) prepare and file with the
     Commission an appropriate amendment to the Registration Statement or
     supplement to the Prospectus or (ii) prepare and file with the Commission
     an appropriate filing under the Securities Exchange Act of 1934 which shall
     be incorporated by reference in the Prospectus so that the Prospectus as so
     amended or supplemented will not, in the light of the circumstances when it
     is so delivered, be misleading, or so that the Prospectus will comply with
     the law in all material respects.

          (f)  The Company will make generally available to its security
     holders, as soon as it is practicable to do so, but in any event not later
     than 15 months after the effective date of the Registration Statement, an
     earning statement (which need not be audited) in reasonable detail,
     covering a period of at least 12 consecutive months beginning after the
     effective date of the Registration Statement, which earning statement shall
     satisfy the requirements of Section 11(a) of the Act and Rule 158 of the
     Rules and Regulations and will advise you in writing when such statement
     has been so made available.

                                     -10-

 
          (g)  The Company will, for a period of five years from the Closing
     Date, deliver to the Representatives copies of annual reports and copies of
     all other documents, reports and information furnished by the Company to
     its stockholders or filed with any securities exchange pursuant to the
     requirements of such exchange or with the Commission pursuant to the Act or
     the Exchange Act.

          (h)  No offering, sale, short sale or other disposition of any shares
     of Common Stock of the Company or other securities convertible into or
     exchangeable or exercisable for shares of Common Stock or derivative of
     Common Stock (or agreement for such) will be made for a period of 90 days
     after the date of this Agreement, directly or indirectly, by the Company
     otherwise than hereunder or with the prior written consent of Alex. Brown &
     Sons Incorporated, except that the Company may, without such consent, issue
     options granted pursuant to plans identified in the Prospectus.

          (i)  The Company will use all commercially reasonable efforts to list,
     subject to notice of issuance, the Shares on the Nasdaq Stock Market.

          (j)  The Company has caused each officer and director and specific
     shareholders of the Company to furnish to you, on or prior to the date of
     this agreement, a letter or letters, in form and substance satisfactory to
     the Underwriters, pursuant to which each such person shall agree not to
     offer, sell, sell short or otherwise dispose of any shares of Common Stock
     of the Company or other capital stock of the Company, or any other
     securities convertible, exchangeable or exercisable for Common Shares or
     derivative of Common Shares owned by such person or request the
     registration for the offer or sale of any of the foregoing (or as to which
     such person has the right to direct the disposition of) for a period of 90
     days after the date of this Agreement, directly or indirectly, except with
     the prior written consent of Alex. Brown & Sons Incorporated ("Lockup
     Agreements"). Notwithstanding the foregoing, members of the Yeager family
     shall not be prohibited from completing intra-family transfers of shares of
     Class A or Class B Common Stock of the Company.

          (k)  The Company shall not invest, or otherwise use the proceeds
     received by the Company from its sale of the Shares in such a manner as
     would require the Company to register as an investment company under the
     Investment Company Act of 1940, as amended (the "1940 Act").

          (l)  The Company will maintain a transfer agent and, if necessary
     under the jurisdiction of incorporation of the Company, a registrar for the
     Class A Common Stock.

          (m)  The Company will not take, directly or indirectly, any action
     designed to cause or result in, or that has constituted or might reasonably
     be expected to constitute, the stabilization or manipulation of the price
     of any securities of the Company.

                                     -11-

 
     5.   Costs and Expenses.

          The Company will pay all costs, expenses and fees incident to the
     performance of its obligations under this Agreement, including, without
     limiting the generality of the foregoing, the following: accounting fees of
     the Company; the fees and disbursements of counsel for the Company; the
     cost of printing and delivering to, or as requested by, the Underwriters
     copies of the Registration Statement, Preliminary Prospectuses and the
     Prospectus; the costs of reproducing and delivering to, or as requested by
     the Underwriters copies of, this Agreement and the Underwriters' Invitation
     Letter; the filing fees of the Commission; the filing fees of the NASD; and
     the Listing Fee of the Nasdaq Stock Market. The Company shall not, however,
     be required to pay for any of the Underwriters expenses except that, if
     this Agreement shall not be consummated because the conditions in Section 6
     hereof (other than paragraph (d) thereof) are not satisfied, or because
     this Agreement is terminated by the Representatives pursuant to Section 11
     hereof, or by reason of any failure, refusal or inability on the part of
     the Company to perform any undertaking or satisfy any condition of this
     Agreement or to comply with any of the terms hereof on their part to be
     performed, unless such failure to satisfy said condition or to comply with
     said terms is due to the default or omission of any Underwriter, then the
     Company shall reimburse the several Underwriters for reasonable out-of-
     pocket expenses, including fees and disbursements of counsel, reasonably
     incurred in connection with investigating, marketing and proposing to
     market the Shares or in contemplation of performing their obligations
     hereunder; but the Company shall not in any event be liable to any of the
     several Underwriters for damages on account of loss of anticipated profits
     from the sale by them of the Shares. 

     6.   Conditions of Obligations of the Underwriters.

          The several obligations of the Underwriters to purchase the Firm
     Shares on the Closing Date and the Option Shares, if any, on the Option
     Closing Date are subject to the accuracy in all material respects, as of
     the Closing Date or the Option Closing Date, as the case may be, of the
     representations and warranties of the Company contained herein, and to the
     performance in all material respects by the Company of its covenants and
     obligations hereunder and to the following additional conditions:

          (a)  The Registration Statement and all post-effective amendments
     thereto shall have become effective and any and all filings required by
     Rule 424 and Rule 430A of the Rules and Regulations shall have been made,
     and any request of the Commission for additional information (to be
     included in the Registration Statement or otherwise) shall have been
     disclosed to the Representatives and complied with to the Representatives'
     reasonable satisfaction. No stop order suspending the effectiveness of the
     Registration Statement, as amended from time to time, shall have been
     issued and no proceedings for that purpose shall have been taken or, to the
     knowledge of the Company, shall be

                                     -12-

 
     threatened by the Commission and no injunction, restraining order, or order
     of any nature by a Federal or state court of competent jurisdiction shall
     have been issued as of the Closing Date which would prevent the issuance of
     the Shares.

          (b)  The Representatives shall have received on the Closing Date or
     the Option Closing Date, as the case may be, the opinion of Mayer, Brown &
     Platt, counsel for the Company, dated the Closing Date or the Option
     Closing Date, as the case may be, addressed to the Underwriters (and
     stating that it may be relied upon by counsel to the Underwriters) to the
     effect that:

               (i)  The Company has been duly organized and is validly existing
          as a corporation in good standing under the laws of the State of
          Delaware, with corporate power and authority to own or lease its
          properties and conduct its business as described in the Registration
          Statement; each of the Subsidiaries has been duly organized and is
          validly existing as a corporation, limited liability company, limited
          partnership or general partnership, as the case may be, in good
          standing, if applicable, under the laws of the jurisdiction of its
          incorporation or organization, with power and authority to own or
          lease its properties and conduct its business as described in the
          Registration Statement; the Company and each of the Subsidiaries are
          duly qualified to transact business in all jurisdictions in which the
          conduct of their business requires such qualification, except where
          the failure to be so qualified would not result in any material
          adverse change in the earnings, business, management, properties,
          assets, rights, operations or condition (financial or otherwise) of
          the Company and the Subsidiaries taken as a whole; and the outstanding
          shares of capital stock of each of the corporate Subsidiaries and the
          partnership interests in each of the partnership Subsidiaries have
          been duly authorized, if applicable, and validly issued and, except
          for general partnership interests, are fully paid and non-assessable,
          and are owned by the Company or a Subsidiary; and, to the best of such
          counsel's knowledge, with the exception of the Company's option to
          acquire the limited partnership interest in each of the Hub
          Partnerships upon the occurrence of certain events, the outstanding
          shares of capital stock of each of the corporate Subsidiaries and the
          partnership interests in each of the Hub Partnerships owned by the
          Company, directly or indirectly, are owned free and clear of all
          liens, encumbrances and equities and claims, and no options, warrants
          or other rights to purchase, agreements or other obligations to issue
          or other rights to convert any obligations into any shares of capital
          stock or of ownership interests in the Subsidiaries are outstanding.

               (ii) The Company has authorized and outstanding capital stock as
          set forth under the caption "Capitalization" in the Prospectus; the
          authorized shares of the Company's Class A and Class B Common Stock
          have been duly authorized; the outstanding shares of the Company's
          Class A and Class B Common Stock have been duly authorized and validly
          issued and are fully paid and non-assessable; the

                                     -13-

 
          Shares conform in all material respects to the description thereof
          contained in the Prospectus; the certificates for the Shares are in
          due and proper form; the shares of Class A Common Stock, including the
          Option Shares, if any, to be sold by the Company pursuant to this
          Agreement have been duly authorized and will be validly issued, fully
          paid and non-assessable when issued and paid for as contemplated by
          this Agreement; and no preemptive rights of stockholders of the
          Company exist with respect to any of the Shares or the issue or sale
          thereof.

               (iii) Except as described in or contemplated by the Prospectus,
          to the knowledge of such counsel, there are no outstanding securities
          of the Company convertible or exchangeable into or evidencing the
          right to purchase or subscribe for any shares of capital stock of the
          Company and there are no outstanding or authorized options, warrants
          or rights of any character obligating the Company to issue any shares
          of its capital stock or any securities convertible or exchangeable
          into or evidencing the right to purchase or subscribe for any shares
          of such stock; and except as described in the Prospectus, to the
          knowledge of such counsel, no holder of any securities of the Company
          or any other person has the right, contractual or otherwise, to cause
          the Company to sell or otherwise issue to them, or to permit them to
          underwrite the sale of, any of the Shares or the right to have any
          Class A Common Stock or Class B Common Stock or other securities of
          the Company included in the Registration Statement or the right, as a
          result of the filing of the Registration Statement, to require
          registration under the Act of any shares of Class A Common Stock and
          Class B Common Stock or other securities of the Company.

               (iv) The Registration Statement has become effective under the
          Act and, to the best of the knowledge of such counsel, no stop order
          proceedings with respect thereto have been instituted or are pending
          or threatened under the Act.

               (v)  The Registration Statement, the Prospectus and each
          amendment or supplement thereto and document incorporated by reference
          therein comply as to form in all material respects with the
          requirements of the Act and the applicable rules and regulations
          thereunder (except that such counsel need express no opinion as to the
          financial statements and related schedules therein). The conditions
          for the use of Form S-3, set forth in the General Instructions
          thereto, have been satisfied.

               (vi) Such counsel does not know of any contracts or documents
          required to be filed as exhibits or incorporated by reference to the
          Registration Statement or described in the Registration Statement or
          the Prospectus which are not so filed, incorporated by reference, or
          described as required, and such contracts and documents as are
          summarized in the Registration Statement or the Prospectus are fairly
          summarized in all material respects.

                                     -14-

 
               (vii)  Such counsel knows of no material legal or governmental
          proceedings pending or threatened against the Company or any of the
          Subsidiaries except as set forth in the Prospectus.

               (viii) The execution and delivery of this Agreement and the
          consummation of the transactions herein contemplated do not and will
          not conflict with or result in a breach of any of the terms or
          provisions of, or constitute a default under, the Charter, By-Laws or
          partnership agreements of the Company or any Subsidiary or any
          material agreement or instrument known to such counsel to which the
          Company or any Subsidiary is a party or by which the Company or any
          Subsidiary may be bound.

               (ix) This Agreement has been duly authorized, executed and
          delivered by the Company.

               (x)  No approval, consent, order, authorization, designation,
          declaration or filing by or with any regulatory, administrative or
          other governmental body is necessary in connection with the execution
          and delivery of this Agreement and the consummation of the
          transactions herein contemplated (other than as may be required by the
          NASD or as required by State securities and Blue Sky laws as to which
          such counsel need express no opinion) except such as have been
          obtained or made, specifying the same.

               (xi) The Company is not, and will not become, as a result of the
          consummation of the transactions contemplated by this Agreement, and
          application of the net proceeds therefrom as described in the
          Prospectus, required to register as an investment company under the
          1940 Act.

          In rendering such opinion Mayer, Brown & Platt may rely as to matters
     governed by the laws of states other than Delaware or Illinois or Federal
     laws on local counsel in such jurisdictions, provided that in each case
     Mayer, Brown & Platt shall state that they believe that they and the
     Underwriters are justified in relying on such other counsel. In rendering
     such opinions, Mayer, Brown & Platt may rely, as to matters of fact, upon
     certificates of public officials and officers of the Company and its
     Subsidiaries. In addition to the matters set forth above, such opinion
     shall also include a statement to the effect that nothing has come to the
     attention of such counsel which leads them to believe that (i) the
     Registration Statement, at the time it became effective under the Act (but
     after giving effect to any modifications incorporated therein pursuant to
     Rule 430A under the Act) contained an untrue statement of a material fact
     or omitted to state a material fact required to be stated therein or
     necessary to make the statements therein not misleading, and (ii) the
     Prospectus, or any supplement thereto, on the date it was filed pursuant to
     the Rules and Regulations and as of the Closing Date or the Option Closing
     Date, as the case

                                     -15-

 
     may be, contained an untrue statement of a material fact or omitted to
     state a material fact necessary in order to make the statements, in the
     light of the circumstances under which they are made, not misleading
     (except that such counsel need express no view as to financial statements,
     schedules and statistical information therein). With respect to such
     statement, Mayer, Brown & Platt may state that their belief is based upon
     the procedures set forth therein, but is without independent check and
     verification.

          (c)  The Representatives shall have received from Piper & Marbury
     L.L.P., counsel for the Underwriters, an opinion dated the Closing Date or
     the Option Closing Date, as the case may be, substantially to the effect
     specified in subparagraphs (ii), (iii), (iv) and (ix) of Paragraph (b) of
     this Section 6, and that the Company is a duly organized and validly
     existing corporation under the laws of the State of Delaware. In addition
     to the matters set forth above, such opinion shall also include a statement
     to the effect that nothing has come to the attention of such counsel which
     leads them to believe that (i) the Registration Statement, or any amendment
     thereto, as of the time it became effective under the Act (but after giving
     effect to any modifications incorporated therein pursuant to Rule 430A
     under the Act) as of the Closing Date or the Option Closing Date, as the
     case may be, contained an untrue statement of a material fact or omitted to
     state a material fact required to be stated therein or necessary to make
     the statements therein not misleading, and (ii) the Prospectus, or any
     supplement thereto, on the date it was filed pursuant to the Rules and
     Regulations and as of the Closing Date or the Option Closing Date, as the
     case may be, contained an untrue statement of a material fact or omitted to
     state a material fact, necessary in order to make the statements, in the
     light of the circumstances under which they are made, not misleading
     (except that such counsel need express no view as to financial statements,
     schedules and statistical information therein). With respect to such
     statement, Piper & Marbury L.L.P. may state that their belief is based upon
     the procedures set forth therein, but is without independent check and
     verification.

          (d)  You shall have received, on each of the dates hereof, the Closing
     Date and the Option Closing Date, as the case may be, a letter dated the
     date hereof, the Closing Date or the Option Closing Date, as the case may
     be, in form and substance satisfactory to you, of Arthur Andersen LLP
     confirming that they are independent public accountants within the meaning
     of the Act and the applicable published Rules and Regulations thereunder
     and stating that in their opinion the financial statements and schedules
     examined by them and included in the Registration Statement comply in form
     in all material respects with the applicable accounting requirements of the
     Act and the related published Rules and Regulations; and containing such
     other statements and information as is ordinarily included in accountants'
     "comfort letters" to Underwriters with respect to the financial statements
     and certain financial and statistical information contained in the
     Registration Statement and Prospectus.

                                     -16-

 
          (e)  The Representatives shall have received on the Closing Date or
     the Option Closing Date, as the case may be, a certificate or certificates
     of the Chief Executive Officer and the Vice President Finance and Chief
     Financial Officer of the Company to the effect that, as of the Closing Date
     or the Option Closing Date, as the case may be, each of them severally
     represents as follows:

               (i) under the Act and no stop order suspending the effectiveness
          of the Registration Statement has been issued, and, to his knowledge,
          no proceedings for such purpose have been taken or are threatened by
          the Commission;

               (ii)  The representations and warranties of the Company contained
          in Section 1 hereof are true and correct in all material respects as
          of the Closing Date or the Option Closing Date, as the case may be;

               (iii)  All filings required to have been made pursuant to Rules
          424 or 430A under the Act have been made;

               (iv)  He has examined the Registration Statement and the
          Prospectus and, in his or her opinion, as of the effective date of the
          Registration Statement, the statements contained in the Registration
          Statement were true and correct in all material respects, and such
          Registration Statement and Prospectus did not omit to state a material
          fact required to be stated therein or necessary in order to make the
          statements therein not misleading, and since the effective date of the
          Registration Statement, no event has occurred which should have been
          set forth in a supplement to or an amendment of the Prospectus which
          has not been so set forth in such supplement or amendment; and

               (v)  Since the respective dates as of which information is given
          in the Registration Statement and Prospectus, there has not been any
          material adverse change or any development involving a prospective
          material adverse change in or affecting the earnings, business,
          management, properties, assets, rights, operations or condition
          (financial or otherwise) of the Company and the Subsidiaries taken as
          a whole, whether or not arising in the ordinary course of business.

          (f)  The Company shall have furnished to the Representatives such
     further certificates and documents confirming the representations and
     warranties, covenants and conditions contained herein and related matters
     as the Representatives may reasonably have requested.

          (g)  The Firm Shares and Option Shares, if any, have been approved for
     designation upon notice of issuance on the Nasdaq Stock Market.

                                     -17-

 
          (h)  The Lockup Agreements described in Section 4(j) are in full force
     and effect.

          The opinions and certificates mentioned in this Agreement shall be
     deemed to be in compliance with the provisions hereof only (i) if they are
     in the form specified herein or (ii) if not in the form specified herein,
     if they are in all material respects satisfactory to the Representatives
     and to Piper & Marbury L.L.P.

          If any of the conditions hereinabove provided for in this Section 6
     shall not have been fulfilled when and as required by this Agreement to be
     fulfilled, the obligations of the Underwriters hereunder may be terminated
     by the Representatives by notifying the Company of such termination in
     writing or by telegram at or prior to the Closing Date or the Option
     Closing Date, as the case may be.

          In such event, the Company and the Underwriters shall not be under any
     obligation to each other (except to the extent provided in Sections 5 and 8
     hereof).

     7.   Conditions of the Obligations of the Seller.
          --------------------------------------------

          The obligations of the Seller to sell and deliver the Shares required
     to be delivered as and when specified in this Agreement are subject to the
     conditions that at the Closing Date or the Option Closing Date, as the case
     may be, no stop order suspending the effectiveness of the Registration
     Statement shall have been issued and in effect or proceedings therefor
     initiated or threatened.

     8.   Indemnification.
          ----------------
   
          (a)  The Company agrees to indemnify and hold harmless each
     Underwriter and each person, if any, who controls any Underwriter within
     the meaning of the Act, against any losses, claims, damages or liabilities
     to which such Underwriter or any such controlling person may become subject
     under the Act or otherwise, insofar as such losses, claims, damages or
     liabilities (or actions or proceedings in respect thereof) arise out of or
     are based upon (i) any untrue statement or alleged untrue statement of any
     material fact contained in the Registration Statement, any Preliminary
     Prospectus, the Prospectus or any amendment or supplement thereto, or (ii)
     the omission or alleged omission to state therein a material fact required
     to be stated therein or necessary to make the statements therein not
     misleading; and will reimburse each Underwriter and each such controlling
     person upon demand for any legal or other expenses reasonably incurred by
     such Underwriter or such controlling person in connection with
     investigating or defending any such loss, claim, damage or liability,
     action or proceeding or in responding to a subpoena or governmental inquiry
     related to the offering of the Shares, whether or not such Underwriter or
     controlling person is a party to any action or proceeding; provided,
     however, that the Company will not be liable (i) in any such case to the
     extent that any such loss, claim, damage or liability arises out of or is
     based upon an untrue statement or

                                     -18-

 
     alleged untrue statement, or omission or alleged omission made in the
     Registration Statement, any Preliminary Prospectus, the Prospectus, or such
     amendment or supplement, in reliance upon and in conformity with written
     information furnished to the Company by or through the Representatives
     specifically for use in the preparation thereof or (ii) to an Underwriter
     with respect to any Preliminary Prospectus, or with respect to any
     Prospectus that has been amended or supplemented to reflect an event
     subsequent to the effective date of the Registration Statement, to the
     extent that any such loss, claim, damage or liability of such Underwriter
     results from the fact that such Underwriter sold Shares to a person to whom
     there was not sent or given, at or prior to the written confirmation of
     such sale, a copy of the Prospectus as then amended or supplemented if the
     Company has previously furnished copies thereof to such Underwriter.

          (b)  Each Underwriter severally and not jointly will indemnify and
     hold harmless the Company, each of its directors, each of its officers who
     have signed the Registration Statement and each person, if any, who
     controls the Company within the meaning of the Act, against any losses,
     claims, damages or liabilities to which the Company or any such director,
     officer or controlling person may become subject under the Act or
     otherwise, insofar as such losses, claims, damages or liabilities (or
     actions or proceedings in respect thereof) arise out of or are based upon
     (i) any untrue statement or alleged untrue statement of any material fact
     contained in the Registration Statement, any Preliminary Prospectus, the
     Prospectus or any amendment or supplement thereto, or (ii) the omission or
     the alleged omission to state therein a material fact required to be stated
     therein or necessary to make the statements therein not misleading in the
     light of the circumstances under which they were made; and will reimburse
     any legal or other expenses reasonably incurred by the Company or any such
     director, officer or controlling person in connection with investigating or
     defending any such loss, claim, damage, liability, action or proceeding
     whether or not the applicable party or controlling person is a party to any
     action or proceeding; provided, however, that each Underwriter will be
     liable in each case to the extent, but only to the extent, that such untrue
     statement or alleged untrue statement or omission or alleged omission has
     been made in the Registration Statement, any Preliminary Prospectus, the
     Prospectus or such amendment or supplement, in reliance upon and in
     conformity with written information furnished to the Company by or through
     the Representatives specifically for use in the preparation thereof. This
     indemnity agreement will be in addition to any liability which such
     Underwriter may otherwise have.

          (c)  In case any proceeding (including any governmental investigation)
     shall be instituted involving any person in respect of which indemnity may
     be sought pursuant to this Section 8, such person (the "indemnified party")
     shall promptly notify the person against whom such indemnity may be sought
     (the "indemnifying party") in writing. No indemnification provided for in
     Section 8(a) or (b) shall be available to any party who shall fail to give
     notice as provided in this Section 8(c) if the party to whom notice was not
     given was unaware of the proceeding to which such notice would have related
     and
        
                                     -19-

 
     was materially prejudiced by the failure to give such notice, but the
     failure to give such notice shall not relieve the indemnifying party or
     parties from any liability which it or they may have to the indemnified
     party for contribution or otherwise than on account of the provisions of
     Section 8(a) or (b). In case any such proceeding shall be brought against
     any indemnified party and it shall notify the indemnifying party of the
     commencement thereof, the indemnifying party shall be entitled to
     participate therein and, to the extent that it shall wish, jointly with any
     other indemnifying party similarly notified, to assume the defense thereof,
     with counsel satisfactory to such indemnified party and shall pay as
     incurred the fees and disbursements of such counsel related to such
     proceeding. In any such proceeding, any indemnified party shall have the
     right to retain its own counsel at its own expense. Notwithstanding the
     foregoing, the indemnifying party shall pay as incurred (or within 30 days
     of presentation) the fees and expenses of the counsel retained by the
     indemnified party in the event (i) the indemnifying party and the
     indemnified party shall have mutually agreed to the retention of such
     counsel, (ii) the named parties to any such proceeding (including any
     impleaded parties) include both the indemnifying party and the indemnified
     party and representation of both parties by the same counsel would be
     inappropriate due to actual or potential differing interests between them
     or (iii) the indemnifying party shall have failed to assume the defense and
     employ counsel acceptable to the indemnified party within a reasonable
     period of time after notice of commencement of the action. It is understood
     that the indemnifying party shall not, in connection with any proceeding or
     related proceedings in the same jurisdiction, be liable for the reasonable
     fees and expenses of more than one separate firm for all such indemnified
     parties. Such firm shall be designated in writing by you in the case of
     parties indemnified pursuant to Section 8(a) and by the Company in the case
     of parties indemnified pursuant to Section 8(b). The indemnifying party
     shall not be liable for any settlement of any proceeding effected without
     its written consent but if settled with such consent or if there be a final
     judgment for the plaintiff, the indemnifying party agrees to indemnify the
     indemnified party from and against any loss or liability by reason of such
     settlement or judgment. In addition, the indemnifying party will not,
     without the prior written consent of the indemnified party, settle or
     compromise or consent to the entry of any judgment in any pending or
     threatened claim, action or proceeding of which indemnification may be
     sought hereunder (whether or not any indemnified party is an actual or
     potential party to such claim, action or proceeding) unless such
     settlement, compromise or consent includes an unconditional release of each
     indemnified party from all liability arising out of such claim, action or
     proceeding.

          (d)  If the indemnification provided for in this Section 8 is
     applicable by its terms but is otherwise unavailable to or insufficient to
     hold harmless an indemnified party under Section 8(a) or (b) above in
     respect of any losses, claims, damages or liabilities (or actions or
     proceedings in respect thereof) referred to therein, then each indemnifying
     party shall contribute to the amount paid or payable by such indemnified
     party as a result of such losses, claims, damages or liabilities (or
     actions or proceedings in respect thereof) in such proportion as is
     appropriate to reflect the relative benefits received by the

                                     -20-

 
     Company on the one hand and the Underwriters on the other from the offering
     of the Shares. If, however, the allocation provided by the immediately
     preceding sentence is not permitted by applicable law then each
     indemnifying party shall contribute to such amount paid or payable by such
     indemnified party in such proportion as is appropriate to reflect not only
     such relative benefits but also the relative fault of the Company on the
     one hand and the Underwriters on the other in connection with the
     statements or omissions which resulted in such losses, claims, damages or
     liabilities, (or actions or proceedings in respect thereof), as well as any
     other relevant equitable considerations. The relative benefits received by
     the Company on the one hand and the Underwriters on the other shall be
     deemed to be in the same proportion as the total net proceeds from the
     offering (before deducting expenses) received by the Company bear to the
     total underwriting discounts and commissions received by the Underwriters,
     in each case as set forth in the table on the cover page of the Prospectus.
     The relative fault shall be determined by reference to, among other things,
     whether the untrue or alleged untrue statement of a material fact or the
     omission or alleged omission to state a material fact relates to
     information supplied by the Company on the one hand or the Underwriters on
     the other and the parties' relative intent, knowledge, access to
     information and opportunity to correct or prevent such statement or
     omission.

          The Company and the Underwriters agree that it would not be just and
     equitable if contributions pursuant to this Section 8(d) were determined by
     pro rata allocation (even if the Underwriters were treated as one entity
     for such purpose) or by any other method of allocation which does not take
     account of the equitable considerations referred to above in this Section
     8(d). The amount paid or payable by an indemnified party as a result of the
     losses, claims, damages or liabilities (or actions or proceedings in
     respect thereof) referred to above in this Section 8(d) shall be deemed to
     include any legal or other expenses reasonably incurred by such indemnified
     party in connection with investigating or defending any such action or
     claim. Notwithstanding the provisions of this subsection (d), (i) no
     Underwriter shall be required to contribute any amount in excess of the
     underwriting discounts and commissions applicable to the Shares purchased
     by such Underwriter, and (ii) no person guilty of fraudulent
     misrepresentation (within the meaning of Section 11(f) of the Act) shall be
     entitled to contribution from any person who was not guilty of such
     fraudulent misrepresentation. The Underwriters' obligations in this Section
     8(d) to contribute are several in proportion to their respective
     underwriting obligations and not joint.

          (e) In any proceeding relating to the Registration Statement, any
     Preliminary Prospectus, the Prospectus or any supplement or amendment
     thereto, each party against whom contribution may be sought under this
     Section 8 hereby consents to the jurisdiction of any court having
     jurisdiction over any other contributing party, agrees that process issuing
     from such court may be served upon him or it by any other contributing
     party and consents to the service of such process and agrees that any other
     contributing party may

                                     -21-

 
     join him or it as an additional defendant in any such proceeding in which
     such other contributing party is a party.

          (f)  Any losses, claims, damages, liabilities or expenses for which an
     indemnified party is entitled to indemnification or contribution under this
     Section 8 shall be paid by the indemnifying party to the indemnified party
     as such losses, claims, damages, liabilities or expenses are incurred.  The
     indemnity and contribution agreements contained in this Section 8 and the
     representations and warranties of the Company set forth in this Agreement
     shall remain operative and in full force and effect, regardless of (i) any
     investigation made by or on behalf of any Underwriter or any person
     controlling any Underwriter, the Company, its directors or officers or any
     persons controlling the Company, (ii) acceptance of any Shares and payment
     therefor hereunder, and (iii) any termination of this Agreement.  A
     successor to any Underwriter, or to the Company, its directors or officers,
     or any person controlling the Company shall be entitled to the benefits of
     the indemnity, contribution and reimbursement agreements contained in this
     Section 8.

     9.   Default by Underwriters.
          ------------------------

          If on the Closing Date or the Option Closing Date, as the case may be,
     any Underwriter shall fail to purchase and pay for the portion of the
     Shares which such Underwriter has agreed to purchase and pay for on such
     date (otherwise than by reason of any default on the part of the Company),
     you, as Representatives of the Underwriters, shall use your reasonable
     efforts to procure within 36 hours thereafter one or more of the other
     Underwriters, or any others, to purchase from the Company such amounts as
     may be agreed upon and upon the terms set forth herein, the Firm Shares or
     Option Shares, as the case may be, which the defaulting Underwriter or
     Underwriters failed to purchase. If during such 36 hours you, as such
     Representatives, shall not have procured such other Underwriters, or any
     others, to purchase the Firm Shares or Option Shares, as the case may be,
     agreed to be purchased by the defaulting Underwriter or Underwriters, then
     (a) if the aggregate number of shares with respect to which such default
     shall occur does not exceed 10% of the Firm Shares or Option Shares, as the
     case may be, covered hereby, the other Underwriters shall be obligated,
     severally, in proportion to the respective numbers of Firm Shares or Option
     Shares, as the case may be, which they are obligated to purchase hereunder,
     to purchase the Firm Shares or Option Shares, as the case may be, which
     such defaulting Underwriter or Underwriters failed to purchase, or (b) if
     the aggregate number of shares of Firm Shares or Option Shares, as the case
     may be, with respect to which such default shall occur exceeds 10% of the
     Firm Shares or Option Shares, as the case may be, covered hereby, the
     Company or you as the Representatives of the Underwriters will have the
     right, by written notice given within the next 36-hour period to the
     parties to this Agreement, to terminate this Agreement without liability on
     the part of the non-defaulting Underwriters or of the Company except to the
     extent provided in Section 8 hereof. In the event of a default by any
     Underwriter or

                                     -22-

 
     Underwriters, as set forth in this Section 9, the Closing Date or Option
     Closing Date, as the case may be, may be postponed for such period, not
     exceeding seven days, as you, as Representatives, may determine in order
     that the required changes in the Registration Statement or in the
     Prospectus or in any other documents or arrangements may be effected. The
     term "Underwriter" includes any person substituted for a defaulting
     Underwriter. Any action taken under this Section 9 shall not relieve any
     defaulting Underwriter from liability in respect of any default of such
     Underwriter under this Agreement.

     10.  Notices.
          ------- 
 
          All communications hereunder shall be in writing and, except as
     otherwise provided herein, will be mailed, delivered, telecopied or
     telegraphed and confirmed as follows: if to the Underwriters, to Alex.
     Brown & Sons Incorporated, 135 East Baltimore Street, Baltimore, Maryland
     21202, Attention: William M. Legg, Managing Director; with a copy to Alex.
     Brown & Sons Incorporated, 135 East Baltimore Street, Baltimore, Maryland

     11.  Termination.
          ----------- 

          This Agreement may be terminated by you by notice to the Company as
          follows:

          (a)  at any time prior to the Closing Date if any of the following has
     occurred: (i) since the respective dates as of which information is given
     in the Registration Statement and the Prospectus, any material adverse
     change or any development involving a prospective material adverse change
     in or affecting the earnings, business, management, properties, assets,
     rights, operations or condition (financial or otherwise) of the Company and
     its Subsidiaries taken as a whole, whether or not arising in the ordinary
     course of business, (ii) any outbreak or escalation of hostilities or
     declaration of war or national emergency or other national or international
     calamity or crisis or change in economic or political conditions if the
     effect of such outbreak, escalation, declaration, emergency, calamity,
     crisis or change on the financial markets of the United States would, in
     your reasonable judgment, make it impracticable to market the Shares or to
     enforce contracts for the sale of the Shares, or (iii) trading generally
     shall have been suspended or materially limited on or by, as the case may
     be, any of the New York Stock Exchange, the American Stock Exchange, the
     NASD, the Chicago Board of Options Exchange, the Chicago Mercantile
     Exchange or the Chicago Board of Trade, (iv) the enactment, publication,
     decree or other promulgation of any statute, regulation, rule or order of
     any court or other governmental authority which in your opinion materially
     and adversely affects or may materially and adversely affect the business
     or operations of the Company, (v) declaration of a banking moratorium by
     United States or New York State authorities,

                                     -23-

 
     (vi) the suspension of trading of the Company's Class A Common Stock on the
     Nasdaq Stock Market or (vii) the taking of any action by any governmental
     body or agency in respect of its monetary or fiscal affairs which in your
     reasonable opinion has a material adverse effect on the securities markets
     in the United States; or

          (b)  as provided in Sections 6 and 9 of this Agreement.

     12.  Successors.
          -----------

          This Agreement has been and is made solely for the benefit of the
     Underwriters and, the Company and its successors, executors,
     administrators, heirs and assigns, and the officers, directors and
     controlling persons referred to herein, and no other person will have any
     right or obligation hereunder. No purchaser of any of the Shares from any
     Underwriter shall be deemed a successor or assign merely because of such
     purchase.

     13.  Information Provided by Underwriters.
          -------------------------------------

          The Company and the Underwriters acknowledge and agree that the only
     information furnished or to be furnished by any Underwriter to the Company
     for inclusion in any Prospectus or the Registration Statement consists of
     the information set forth in the last paragraph on the front cover page
     (insofar as such information relates to the Underwriters), legends required
     by Item 502(d) of Regulation S-K under the Act and the information under
     the caption "Underwriting" in the Prospectus.

     14.  Miscellaneous.
          --------------

          The reimbursement, indemnification and contribution agreements
     contained in this Agreement and the representations, warranties and
     covenants in this Agreement shall remain in full force and effect
     regardless of (a) any termination of this Agreement, (b) any investigation
     made by or on behalf of any Underwriter or controlling person thereof, or
     by or on behalf of the Company or its directors or officers and (c)
     delivery of and payment for the Shares under this Agreement. 

          This Agreement may be executed in two or more counterparts, each of
     which shall be deemed an original, but all of which together shall
     constitute one and the same instrument.

          This Agreement shall be governed by, and construed in accordance
     with, the laws of the State of Maryland.
